M5stack module 13.2 LAN

M5stack module 13.2 LAN


LAN Module 13.2 is a powerful Ethernet controller module that integrates the W5500 hardware TCP/IP embedded Ethernet controller (via SPI communication interface). It supports multiple communication protocols and is suitable for various applications such as industrial automation, Internet of Things (IoT), data acquisition, and remote monitoring.

LAN Module 13.2 features the built-in W5500 hardware TCP/IP embedded Ethernet controller, which supports TCP, UDP, IPv4, and other communication protocols to meet the requirements of different application scenarios. Additionally, the module integrates a storage buffer area to handle Ethernet data packets efficiently. Equipped with a signal-isolated gigabit transformer, LAN Module 13.2 converts the input signals from the RJ45 interface to the appropriate output signals, achieving electrical isolation and preventing electromagnetic interference. This enhances system stability and reliability.

LAN Module 13.2 supports a DC-JACK interface (9-24V) and a DC-DC buck circuit, simplifying power management and providing a reliable power supply for the entire device. The module includes a built-in jumper pin for chip selection, allowing two modules to be stacked simultaneously for dual Ethernet connectivity. It also provides a VH3.96 interface for easy integration of additional expansion devices, offering greater flexibility to meet specific application requirements.

In addition to its application as an Ethernet controller, LAN Module 13.2 can be widely used in various scenarios such as Ethernet-to-AP conversion, lightweight web server, and RS485-to-Ethernet data transmission unit (DTU). It enables diverse data transfer and interconnection, providing flexible solutions for users.
